I'm trying to convert html file containing mathematical expression in latex using the following command:

pandoc -i integrals.html -o integrals_doc.docx

   But the output contains latex as  it is. I also tried --mathml flag, but no luck. 

But if the source html file contains expression in mathml, it works fine while converting to docx. 

Similarly, I want to convert it to epub containing mathml expression, because the epub-reader we are targeting only support mathml expression. 

Any leads in this conversion from html containing latex to docx or epub with mathml will be very helpful.

Thanks in anticipation
